My check engine light came on in my 4R. Turns out it was the o2 sensor. The odd thing was that when that when I tried to engage the 4wd with the button it would take about 3-4 minutes to engage 4wd. After I got the o2 sensor replaced it went back to engaging in about 30secs. Initially I thought something else was going on. Never thought the two would have anything to do with each other. Anyone ever heard of this?
